Thank you for attending the 'Infrared Array Sensor Forum 2024'.

Craftsman's Point: Achieving optical properties with a periodically varying refractive index. Applications: Expected applications in notable fields such as Raman spectroscopy.

We will achieve optical characteristics that have not been realized until now by periodically changing the refractive index. Conventional optical filters (optical thin films) consist of alternating layers of high refractive index films and low refractive index films, which exhibit specific optical properties. In contrast, notch filters (band-stop filters) are deposition products designed to periodically change the refractive index in the thickness direction. They are characterized by the absence of optical ripples outside the stopband. We can realize optical characteristics that have not been achievable with conventional optical thin film processing. (Do you have such challenges?) ■ Is it possible to reflect only around the wavelength of 532nm? ■ I would like the unnecessary parts to be unable to transmit optically. ■ Notch filter? Band-stop filter? Rugate filter? ■ I have heard that the measurement difficulty after deposition is high; can you accommodate this?

It is an optical filter that selectively transmits ultraviolet wavelengths (255 nm) while blocking light of other wavelengths (using a substrate from Hisashi Seiko Glass).

Applications in the ultraviolet region are on the rise. At Isuzu Seiko Glass Co., we have developed filter glass substrates (IHU series) that have a transmission limit wavelength in the ultraviolet range and improved weather resistance to ultraviolet light. Recently, we have successfully deposited dielectric multilayer films to create bandpass filters in the ultraviolet range, as shown in the chart (measured data). (Are you facing these challenges?) ■ I want to selectively transmit specific wavelengths using aspherical lenses or lens arrays. ■ Is it possible to achieve pinpoint transmission at the UV-C wavelength of 254 nm? ■ Is it possible to achieve anti-reflection with limited substrates and deposition materials? ■ I've heard that measurement difficulty after deposition is high; can you handle that? ■ Is it true that controlling the thickness in the UV region is very difficult due to its thin film? Based on our achievements in visible light, we can achieve high transmission rates in the ultraviolet wavelength range by controlling the deposition process. Additionally, by leveraging our ability to mold aspherical lenses and lens arrays in combination with our deposition technology, we can propose new applications.

This is an infrared wavelength filter optimized for optics, with plasma control technology enhanced to its limits.

Infrared materials are incredibly fragile! (Weak against scratches, water, and chemicals) This common understanding can be overturned with our company's technology. 1) Excellent infrared transmission characteristics This is a filter that transmits infrared light through the formation of a multilayer film and its interference effect. It achieves excellent transmission rates from the near-infrared to far-infrared regions. 2) Custom design and customization for desired wavelength ranges We can design and deposit films tailored to the wavelength range requested by our customers. Please inform us of the substrate type and wavelength range when making inquiries, as we will design according to the characteristics of the substrate. 3) Measurement equipment: We own FT-IR Rest assured that we will always attach a measurement chart (spectral characteristics) upon shipment. 4) Component support is also possible We can not only procure substrates and deposit films but also cut them into any shape and ship them as components. However, we will need detailed drawings. 5) Cleanroom compliance Our working environment maintains the necessary cleanliness levels from film deposition to inspection, and we have a robust system in place to address minor film defects (such as foreign particles in the film).

[To the owners of parking lots and parking lot construction companies] "I am worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as pedestrian collisions and vehicle-to-vehicle accidents. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask that you arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.

In recent times, there has been a growing interest in infection control measures and facility hygiene management. Our company offers non-contact sensor products that are recommended for commercial facilities, food factories, and nursing and caregiving facilities. 【Sensors for Automatic Doors】 ● Light Touch Sensor HA-T401 … When you wave your hand in front of the automatic door, the sensor detects the movement and opens or closes the door. This is recommended for making doors with touch switches non-contact. ● Hand Wave Sensor PF-R5, PF-U2, DHS-1 … Opens and closes the automatic door by waving your hand in front of the sensor. ● Foot Switch PF-01S/01D/03S/05 … Opens and closes the automatic door by placing your foot in the opening. 【Access Control System】 ● Face Recognition + Unmanned Temperature Measurement DS Series … Allows for face recognition along with mask detection and body temperature measurement simultaneously. ● Automatic Disinfectant Spray Dispenser PHW-03B … Automatically sprays disinfectant when you wave your hand in front of the sensor. 【Nursing and Care Sensors】 ● Infrared Bed Exit Sensor "Just Place It Pole-kun" … This bed exit sensor is installed next to the bed and notifies via nurse call when the subject enters the detection range. ◎ For more details, please download the catalog or contact us.
